VALVE-PLUG REMOVER.

Application filed September 13, 1920.

To all whom t may concern.'

Be it known that l, MICHAEL KEATING, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful improvements in Valve-Plug- Removers, ofwhich the following is a specification. l i

The principal object of my invention is to provide a device that may beemployed readily and successfully with a wrench, to remove a recessedvalve plug'or similar device from an explosive engine or otherstructure. lt may be cheaply and simply constructed, and is adapted forconvenient use by automobile drivers and garage workers.

The preferred form of embodiment of my invention is illustrated in theaccompanying drawings, of which Figure l. is a perspective view of mydevice. Fig. 2 is a top plan view of the latter in the grip of the jawsof a wrench. Fig. 3 is a perspective veiw.of the device fitted into thetop portion of a valve plug. Fig. l is a bottom plan view of my device.And Fig. 5 is a top plan view of the valve plug into which the devicefits.

Throughout the specification and drawings, similar reference charactersdenote corresponding` parts.

Referring to the accompanying drawings, my valve-plug remover comprisesa casting having an annular shoulder l, on one side of which there is acubical projection 2 adapted to be gripped by a wrench 3, and on theother side of which there is a cylindrical projection t adapted to enterthe bore 5 in a valve plug 6 or other part. (See Figs. l and 2.)

cal portion t of the casting, along the b ottom portion of the annularshoulder 1 to the outer periphery thereof, 1s a series of radial ribs orlugs 7, Y, adapted to lit into radial recesses 8, 8, provided in the top(See Figs. 3, e and 5.)

When it is desired to unsorew the valve plug 6 from its socket (notshown), the

to bring the ribs 7, 7 within the recesses 8,

8 of the plug, after which a wrench is applied to the cubical end 2 ofthe casting and the latter rotated by it until the plug is removed. Thisis found to be a much more convenient way of removing the plug 6 than byturning it with a metal plate or other piece inserted in the recesses 8,8.

Afterthe valve plug 6 has been removed by-my device, the latter may beemployed with equal facility to re-insert the plug.

Having described my invention, l claim: A device of the type describedcomprising a member having a middle shoulder portion, a projectionadapted to be gripped by a wrench on one side of said shoulder portion,a cylindrical projection on the other side of said shoulder portion, andlugs pro jecting outwardly from said shoulder' portion along thecylindrical projection distance less than the distance between saidshoulder portion and the outer edge of the cylindrical projection.

ln testimony whereof l have hereunto set my hand this 11th day ofSeptember, 1920.
